Air flows through an axial-flow compressor. The axial velocity is 60% of the blade speed at the mean radius. The degree of reaction is 0.4. The absolute velocity enters the

stator at an angle of 55° from the axial direction. Draw the velocity diagrams at the inlet and outlet of the rotor. Determine the blade-loading coefficient. Determine at what angles the relative velocity enters and leaves the rotor. Determine at what angle the absolute velocity enters the rotor. e) Draw the Moiller diagram of this axial compressor
